VENTILATING ATTACHMENT FOR STOVES.

SPECIFICATION forming part of Letters Patent No. 349,425, dated September 21, 1886.

Original application filed March 25, 1886, Serial No. 196,560. Divided and this application filed July 121, 1886. Serial No. 207,986.

. (No model.)

To all whom it may concern:

Be it known that I, WARREN M. BRINKER- HOFF, a citizen of the United States, residing at Auburn, in the county of Cayuga and State of New York, have invented certain new and useful Improvements in Ventilating Attachments for Stoves; and I do hereby declare the following to be afull, clear, and exact descrip tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This application is a division of application for ventilator attachments for stoves filed March 25, 1886, Serial No. 196,560. The invention included therein relates to ventilating attachments for stoves, and the object thereof is to provide a ventilating-pipe so located that the smoke-outlet. 'which is located in this instance within the stove with the rear wall and smokeflue in section.

Inthe drawing, A deslgnates a stove, and a B is the ventilator-pipe,

stove. This ventilator-pipe communicates with the open air at its lower end and rises adjacent to the wall of the stove, and is pro- .vided with an outward turn and discharges into the smoke-outlet. The discharge end of this ventilator-pipe is made to extend above the lower wall ot'the smoke-outlet. As a result of this construction, the pipe and the air within it are heated by radiation from the wall of the stove and the other parts of the stove adjacent thereto, the heat being greater as the pipe ascends, while that portion of the pipe which 7 extends above the lower wall of the smokeoutlet receives the full force of the hot pr0- ducts of combustion, raising the pipe and its contained air-current'to very nearly their own degree of heat. A strong draft is then secured for the ventilatingpipe and the draft of the stove is in no wise impaired.

I am aware that in mine-ventilation a pipe from the part to be ventilated has been carried to a furnace and introduced into the upright smoke-outlet of the same with an upward turn. I am also aware that astove has been constructed with an air-heating chamber at one side communicating with an upright smoke outlet by a pipe. Such constructions I do not claim; but

What I do claim, and desire toseeure by Letters Patent, is- I 1. The combination, with a stove, of a ventilating-passage separate from the flues of the stove, communicating with the outer air at its lower end, rising therefrom adjacent to the wall of the stove to a point above the lower wall of the smoke-outlet, and provided with an outward turn and discharging into the outlet, substantially as described.

2. The combination, with a stove having an opening through the side of the stovebody, forming the smoke-outlet, of a ventilatingpassage separate from the fines of the stove, communicating with the outer air at its lower end, rising therefrom adjacent to the wall of the stove-body to a point above the lower wall and below the upper wall of the smoke-outlet, and provided with an outward turn and dis charging into the outlet, the said passage having the turn and a portion of its length lying in the path of the products of combustion, substantial] y as described. 'In testimony whereof I afiix my signature in presence of two witnesses.
